An in vitro study of Antioxidant effect of Santalum album, the Indian sandalwood

Abstract

The antioxidant potential of Indian sandalwood, Santalum album, was investigated in this study, by DPPH scavenging, FRAP and hydroxyl radical scavenging in vitro assays. Aqueous extract of sandalwood callus, at concentrations of 25, 50, 75 and 100 micrograms/ml was used. The in vitro studies demonstrated significant antioxidant ability of sandalwood, which was concentration-dependent. At a concentration of 100 micrograms/ml, sandalwood extract showed 48.7% DPPH scavenging, 1 micromoles of ferrous iron/ml (by FRAP assay) and 53.2: scavenging of hydroxyl radicals. Further studies with multiple concentrations and comparison with standard antioxidants are required.
